ENAMELED WARE, 80C.

SPECIFICATION forming part of Letters Patent No. 250,102, dated November29, 1881. Application filed October 3, 1881. (Model.)

To all whom it may concern Be it known that I, EBEN G. QUINBY, a citizenof the United States, residing at St. Louis, in the State of Missouri,have invented certain new and useful Improvements in Enameled Ware andMethod of Constructing the Same, as fully set forth and described in thefollowing specification and illustrated in the accompanying drawing.

My improvement relates to wrought or castmetalenameledware;anditconsistsinfirstcoating the body of an'articlewith enamel of any desirable color and afterward producing thereon inrelief ornaments of some con trastingcolor.

The drawing is a side elevation of a tea-pot illustrating a preferredform of my invention viz., having its body coated with a deep-blueenamel, and the relief ornament in white, silver, or gold.

To enable others to practice my invention, I will now proceed todescribe the best method now known to me of producing the same.

Having first cleaned the article by pickling, turning, or any otherknown method, I cover the same with a solid coat of enamel of anysuitable color and then fire the same. This part of the process may beperformed in any of the known ways, and the color desired may beproduced by the use of the metallic oxides, as is known to all familiarwith the art of enameling, and therefore need not be minutely described,and of itself is not novel. After the article is fired it is taken fromthe muffle and allowed to cool. I next take some glaze mixed with someone of the metal oxides which will produce a pleasing contrast with thecolor of the enamel on the body of the article, using it quite thick,and with this prepared glaze I paint, stamp, stencil, or otherwise putupon thebody-color any selected design or ornament, laying on the samequite thick, and after drying the article thus ornamented it is againfired.

The glaze used in ornamenting is made somewhat softer than the firstcoat, so that the body of the article is not injured by the secondfiring. When the article is taken from the muffle the second time itwill be found that the body is coated with a solid enamel, and theornament of the contrasting color is in relief on the surface thereof,producing a very artistic and pleas ng efi'ect.

Although I do not wish to limit myself to the use of any particularcolor, I have found in practice that I get the best results and thehandsomest ware by using a ground of deep or cobalt blue and paintingthe ornament there on in white, silver, or gold. Any colors may be usedthat contrast well with or are complementary to each other, as whiteground and gold ornaments, green and gold, &c.

.It will be understood that when silver and gold are used the ornamentis first put on with glaze to bring it in relief and fired, and thenagain fired after gilding or silvering.

Having thus fully described my improvement, so that any person skilledinthe art can make and use the same, what I claim as new, and desire tosecure by Letters Patent, is-

1. As a new manufacture, metal ware the body or ground of which isenameled in some solid color, and having thereon in relief ornaments ofsome suitable contrasting color, substantially as set forth.

2. The method of enameling metal ware, which consists in first coatingthe body of the article with glaze of some suitable color, firing thesame, then painting or otherwise placing thereon suitable ornaments inrelief in some contrasting color, and again firing, substantially asherein set forth.
